FastAPI Introduction - Full CRUD API Tutorial - Backend Engineering

Learn to build a complete CRUD (Create, Read, Update, Delete) API using FastAPI, Python's modern web framework for building APIs. Start with FastAPI fundamentals and setup, then progress through building your first API with paths and path parameters. Master GET requests by working with mock data stored in dictionaries and learn how to retrieve both multiple items and single campaigns. Explore API interaction techniques before advancing to mocked POST, PUT, and DELETE operations. Transition from mock data to real database integration by working with SQL databases and implementing lifespan events for proper database management. Build robust data types and seed your database with initial data. Implement comprehensive CRUD operations including GET requests for multiple items and single items by ID, create generic response types for consistent API responses, and handle POST requests for creating new data with custom create types. Complete your API by implementing PUT requests for updating existing data and DELETE requests for removing data from your database.
